Abstract

Abstract:

Objective

To investigate the effect of vacuum sealing drainage on the treatment of necrotizing fasciitis wound after surgery.

Methods

An analysis of patients in the Department of General Surgery of First Affiliated Hospital of Harbin Medical University from January 2013 to January 2018 was actualized. The elected patients were divided into two groups randomly accorcling to the random number table method. The treatment group (n=25) underwent vacuum sealing drainage, and the control group (n=25) underwent conventional dressing change, debridement, irrigation, drainage. Record the states of wound healing rate, granulation tissue score, and visual analogue score on the day of surgery and the 5th, 10th and 15th day after surgery, total hospital days, total dressing changing times and average interval days of dressing changing. Date were processed with paired sample t test and independent sample t test.

Results

There was no significant difference between the two groups in diagnostic criteria of granulation and visual analogue scores on the day of surgery (with P values above 0.05). On the 5th, 10th and 15th day after surgery, there were statistically significant differences in wound healing rates (t=10.184, 10.498, 11.523; with P valuse below 0.05), diagnostic criteria of granulation (t=-4.925, -6.039, -6.647; with P values below 0.05) and visual analogue score (t=-2.918, -3.540, -2.402, with P values below 0.05) between the two groups, the results of the treatment group were better than the control group. The average total hospital days of the treatment group were (19.4±17.1) d, less than the (42.4±13.5 ) d of the control group (t=-5.275, P=0.00048) . The average total dressing changing times of the treatment group were(2.08±1.75) times, the average interval was (9.56±1.60 ) d. The average total dressing changing times of the control group were (20.16±6.63) times, the average interval was (2.11±0.06) d, the differences were statistically significant (t=-13.179, 23.322; with P values below 0.05).

Conclusions

The application of vacuum sealing drainage brings the patients higher wound healing rates, fresher granulation and less pain. Moreover, it reduces the dressing changing times remarkably and improves efficiency, and is worth to be popularized in the treatment of necrotizing fasciitis.
